•• • •
Electrical maintenance officer
• Typical maintenance activities:
• intervention on the electrical equipment beginning from the electrical circuit diagrams.
• test of the execution of movements and electric adjustment of the safety devices.
• check of the wear of electrical components (contacts of the electrical equipment).
• repairs of the electric units after replacement of parts with original spare parts.
• Technical knowledge required:
• good knowledge of electrical plants and installations.
• good knowledge of the electrical componentry and of the safety devices used in the hoist (limit
switches, brakes, etc.).
• knowledge of moderately difficult electrical checks and adjustments (replacement according to
the original diagrams: motors, limit switches, push-button panel, control console, cables, etc.).
• basic knowledge of moderately difficult techniques for mechanical checks and adjustments
(wear testing, adjustment of mechanical stops, etc.).
• knowledge of the methods of measurement and testing to determine the actual state of the
conditions of the hoist (tests of the efficiency and reliability of the electrical equipment).
• knowledge of trouble-shooting methods in case of power failure or breakdown and experience
of electric command and control systems of lifting and handling equipment.
• ability to arrange the necessary measures to put the hoist back into working order.
• ability to write a maintenance intervention report.
• Qualification required:
• Complete training of an industrial electrician having a specialisation in and experience of liftingsystem
maintenance or of industrial handling.
Electromechanical maintenance officer:
He is an operator whose professional profile, as well as including the typical
characteristics of the electrical maintenance officer, also combines and
synthesizes the competence and abilities required of the mechanical
maintenance officer
Mechanical technician
• Typical maintenance activities:
• mechanical adjustments of the safety devices, calibrations and tests (annual load test).
• normal maintenance work after substitution of complex and/or critical mechanical componentry
in order to maintain safety levels (fixing components, arm, reducers, motors,etc.).
• repair of mechanical units after extra maintenance work has been carried out (structural
repairs requiring soldering, mechanical work on board of the crane, etc.).
• Technical knowledge required:
• knowledge of industrial mechanical lifting and handling systems with proof of specific training.
• specific knowledge of safety devices used on the hoist (limit switches, brakes, overload switch,
etc.).
• basic knowledge of techniques for electric checking and adjustment (motor test).
• specific competence about the methods of measurement and testing to determine the actual
state of the conditions of the crane and the hoist (test of: brakes, push-button panel, control
console, limit switch etc.).
• specific competence of logical trouble-shooting methods in case of breakdown and evaluation
of the results.
• ability to direct the necessary measures to put the jib crane back into working order.
• ability to write a maintenance intervention report.
• Qualification required:
•• • • Complete
training as industrial mechanical technician and specific competence in lifting and
handling systems.
